Introduction: Upper urinary tract urothelial carcinoma (UTUC) is a rare disease. Thus, little evidence-based data are available to guide clinical decision-making. The aim of the study was to provide an overview of the currently available prognostic factors for UTUC., Material and Methods: A systematic literature search was conducted using the PubMed databases to identify original articles regarding prognostic factors in patients with UTUC., Results: We divided the prognostic factors for UTUC in four different categories: clinical factors, preoperative characteristics, intraoperative/surgical factors and postoperative/pathologic factors. Prognostic factors described in order of importance are: tumor stage and grade, lymph node involvement, a concomitant cis, age at the diagnostic, lymphovascular invasion, tumor architecture and necrosis, tumor location and multifocality, gender. The impact of obesity, smoking and other comorbidities (ECOG, ASA) on outcomes has been recently reported but needs to be validated. The endoscopic approach of distal ureter management during radical nephroureterectomy has been shown to be at higher risk of bladder recurrence., Conclusion: The incorporation of such prognosticators into clinical prediction models might help to guide decision-making with regard to timing of surveillance, type of treatment, performance of lymphadenectomy, and consideration of neoadjuvant or adjuvant systemic therapies., (Copyright © 2013.

Objectives: To identify predictive factors of bladder recurrence after radical nephroureterectomy and to evaluate the impact of this event on oncological outcomes., Methods: We carried out a retrospective analysis of 237 patients treated with radical nephroureterectomy for urothelial carcinoma of the upper tract at our institution from 1998 to 2011. Univariable and multivariable models evaluated the prognostic factors of bladder recurrence, and its impact on recurrence-free survival and cancer-specific survival., Results: The median age was 69.3 years (interquartile range 60-76). With a median follow up of 44 months (interquartile range 24-79), bladder recurrence occurred in 85 patients (35.9%). A previous history of bladder cancer (P = 0.01) and the presence of concomitant carcinoma in situ (P = 0.005) remained independent predictors of bladder recurrence. The presence of bladder recurrence was not correlated with worse oncological outcomes in terms of disease recurrence (P = 0.075) and cancer-specific mortality (P = 0.06). However, the patients who experienced muscle-invasive bladder cancer recurrence had worse outcomes in terms of cancer-specific mortality (P = 0.01). Standard pathological features of aggressiveness, such as higher tumor stage (P = 0.05), higher grade (P = 0.01) and carcinoma in situ (P = 0.03), were independent predictors of muscle-invasive bladder cancer recurrence., Conclusions: Previous history of bladder cancer, tumor location and concomitant carcinoma in situ are independent predictors of bladder recurrence in patients undergoing radical nephroureterectomy. Bladder recurrence overall does not impact the oncological outcomes, but a muscle-invasive bladder recurrence is associated with a worse cancer-specific mortality. Standard pathological features of urothelial carcinoma of the upper tract aggressiveness (pT-stage, grade) are independent predictors of muscle-invasive bladder cancer recurrence., (© 2013 The Japanese Urological Association.)
